TEILE HENRY MI TLLER, OF NEW YORK, ASSIGN OR TO SAMUEL S. HEPVORTH, OF YONKERS, AND JOSEPH OOLVVELL, OF NINY YORK, N. Y., ONE-HALF TO EACH.

CENTRIFUGAL MACHINE.

SPECIFICATION formingpart of Letters Patent No. 225,631, dated March 16, 1880.

Application filed September 2, 1879.

To all whom it may concern:

Beit known thatI, TEILE H. MiiLLER, ofN ew York, in the county and State of New York,

7 have invented certain new and useful Im- 5 provements in Centrifugal Machines; and I do hereby declare that the following is a full,

clear, and exact description thereof, whereby a person skilled in the art can make and use the same, reference being had to the accomto panying drawings, and to the letters of reference marked thereon.

Like letters in the figures indicate the same parts.

My improvements relate to centrifugal ma- I 5 chines, such as are used for the purging of sugar and for various other purposes, in which the fluid is separated from the mass with which the machine is charged by the action of centrifugal force.

The object of my invention is to provide a better and more durable construction of the valve and its connections, and the mechanism for opening and closing in such centrifugal machines as discharge the contents of the 2 5 basket, after drying, through the bottom, than has heretofore been in use.

My invention consists in the construction and arrangement of the several parts, as will be hereinafter described.

In the accompanying drawings, Figure 1 shows a vertical section through the middle of the machine. Fig. 2 shows a top view of the bottom of the basket, with the top part of the basket and the central parts for operating 35 the valve removed, so as to show the parts beneath.

1 is the basket of a centrifugal machine, constructed in the ordinary manner, and suspended upon a spindle, so that it can be rap- 4 idly revolved.

2 is the spindle, upon which the basket is keyed or otherwise fixed.

3 is the valve, turning under the bottom of the basket and provided with wings, which 5 cover the openings 4. in the bottom when the valve is closed. When the valve is open these wings lie under the solid parts of the bottom, between the openings, so that the sugar or other substance discharges freely through the openings without touching the valve. The wings of the valve are connected by an annular plate which lies inside of the openings in the bottom of the basket and turns in suitable bearings, as will be described.

5 is an annular plate attached to the bottom of the basket to form a bearing for the valve 3, which it supports. It is provided, also, with a downward-projecting rim or flange, for the purpose of protecting the central bearing of the spindle. The top of the plate 5 is made to fit the bottom and inner edge of the valveplate, and it may be provided with springs under the valve or upon its inner edge, to give the proper amount of friction upon the valve and prevent it from turning too freely.

6 is a hollow cone turning upon a central bearing in the basket, and which is provided with a hand-wheel, 7 for operating it to open or close the valve.

8 is a pin which is screwed firmly into the lower edge of the hollow cone 6. There may be two or more of these pins, the number shown in the drawings being three, the same as the valve-openings. These pins move in slots through the bottom of the basket concentric with the axis of the valve, and enter into holes in the valve-plate. By this arrangement whenever the hand-wheel 7 is turned the valve turns with it, the pins moving in the slots shown at 9 in Fig. 2.

10 is a collar upon the spindle, for the purpose of holding the cone 6 down to its place. This collar is fastened by a set-screw. By removing the collar the hollow cone 6, together with the pins, can be lifted up for cleaning or inspection.

The slots are so formed in the bottom of the basket that the valve opens by turning in the same direction as the basket revolves.

By this arrangement the inertia of the valve operates to open it when the brake is put on to stop the revolution of the basket, and to close the valve when the basket is started.

The slots are also inclosed upon the top by the bottom flange of the hollow cone 6,-and upon the bottom by the top of the valve-plate, so as to prevent all clogging by the entrance of the sirup.

I do not claim a valve turning on the under side of the basket of a centrifugal machine; but

WVhat I dovclaim, and desire to secure byv i interior of the basket to an oscillating valve 15 below the bottom, substantially as described.

3. The supporting-plate 5, in combination with the-valve 3 and a removable operating mechanism acting through the bottom of the basket, substantially as described.

4. The combination of the collar 10 with the removable cone 6, the basket 1, and the valve 3, substantially as described.
